Mean values for the fasting serum levels of the individual amino acids are given for 34 adult males and 35 adult females, ranging in age from 20 to 39 years. Threonine plus glutamine, alanine and lysine accounted for about 40% of total amino acids, and total essential amino acids was significantly lower than total nonessential amino acids. There were highly significant differences between men and women in the mean serum amino acid levels. Men had significantly .higher levels than women for most of the amino acids except lysine and histidine. Total essential amino acids, and the molar ratios of total essential to total nonessential amino acids and total amino acids showed significantly higher levels in men than in women. The molar ratios of each essential amino acid to total essential amino acids were also examined.

Fifteen species of wild mushrooms, which are classified as edible, medicinal, poisonous, or unknown types, were analyzed for their free amino acid contents. The average total amino acid content was 1,120.0 mg/kg in the edible type, 1,037.8 mg/kg in the medicinal type, and 1,010.8 mg/kg in the poisonous or unknown type, respectively. The edible type wild mushrooms showed the highest average content of total essential amino acids; conversely, the poisonous or unknown type showed the lowest content. Leucopaxillus giganteus (OK811) showed the highest total amino acid (1,212.4 mg/kg) and essential amino acid (490.2 mg/kg) contents among edible type, while Pycnoporus sanguineus (OK1071) showed the highest total amino acid (1,233.7 mg/kg) and essential amino acid (412.8 mg/kg) contents among the medicinal type. Among the poisonous or unknown type, Hypholoma fasciculare (OK826) showed the highest total amino acid (1,223.4 mg/kg) and essential amino acid (442.8 mg/kg) contents. The amino acid contents of wild mushrooms are fundamental data for the screening of useful genetic resources with nutritionally superior properties.

This study was to investigate the amount of protein and essential amino acid in 19 fast-foods. fast-food samples were freeze dried, then assayed for protein and eight essential amino acids by Kjeldahl and amino acid autoanalyzer method. A.S.(amino acid score) based on FAO/WHO(1973) provi-sional Pattern & C.S.(chemical score) based on whole e99 Pattern(1972) were calculated from the amount of essential amino acid of fast-foods. The 1st limiting amino acid of the tested fast-foods was found to be SAA based on both whole e99 Pattern& FAO/WHO Provisional Pattern.

표고는 단백질, 무기질, 비타민과 같은 영양소가 골고루 함유되어 있고 독특한 맛과 향기를 가지고 있어 식용으로 널리 이용되고 있다. 이들 성분 중 단백질 및 아미노산은 생체기능 및 대사에 관여하는 영양소이며 풍미와도 밀접한 관계를 가지고 있다. 본 연구에서는 국내산표고균주와 수입표고균주의 조단백질과 아미노산 함량을 조사하였으며, 국내산표고균주 4종과 수입표고균주 4종의 함량을 비교하였다. 국내산표고균주의 조단백질 함량은 25.36~34.11%, 수입표고균주는 18.91~28.70%로 나타났으며, 아미노산은 16종류의 아미노산이 분석되었다. 국내산표고균주와 수입표고균주의 구성아미노산 함량은 각각 8,318.66~17,672.59mg%와 9,828.10~16,944.87mg%였다. 국내산표고균주와 수입표고균주의 유리아미노산 함량은 각각 466.78~899.82mg%와 407.12~669.34mg%로 나타났다. 국내산표고균주와 수입표고 균주의 필수아미노산 함량은 각각 27.92~37.67%, 33.74~61.59%로 확인되었다. 수입표고균주의 필수아미노산이 국내산표고균주에 비하여 높은 비율을 나타내었으나, 표고의 아미노산 함량이 차이가 있어 수입산표고균주의 필수아미노산 함량이 국내산보다 높다고 보기는 어렵다. 이러한 결과는 표고의 산업화에 유용한 정보를 제공하고 표고의 영양학적 지표 자료로 활용될 수 있을 것으로 보여지며, 추후 더 많은 시료를 수집하고 분석항목을 다양화한 연구를 지속적으로 진행할 예정이다.

The aim of this study was to examine the effects of Capsosiphon fulvescens extract (CFE) on levels of essential amino acids in serum and the rate of protein digestion. CFE contains approximately 68% carbohydrate as fiber, 17% crude ash, and 14% crude protein. Experimental rats were divided two groups, one group receiving a normal diet and the other a normal diet containing 5% CFE. To analyze the absorption of essential amino acids into the hepatic portal vein, blood from the hepatic portal vein was collected between 10 a.m. and 5 p.m. for 10 days. In vitro protein digestion was decreased in the group fed 5% CFE; these data indicated that CFE affected protease activity. We measured the absorption of essential amino acids in the serum of the hepatic portal vein, at 30-, 60-, 90-, and 120 minutes after feeding. Although there was no difference in the concentration of total essential amino acids between the two groups, the 5% CFE-fed animals had a decreased rate of absorption. Absorption of Lys and Thr into the hepatic portal vein was lower in the CFE-fed group than in the control group. The rate of absorption of Met was delayed nearly 50% in the CFE-fed group compared to the control group. On the other hand, the rate of absorption of Leu, Ile, and Val was increased; Phe showed the same. Therefore, we suggest that CFE could affect protein metabolism by increasing or decreasing the absorption rate of essential amino acids.
